This application is a continuation of U.S. patent application Ser. No. 11/264,371, which was filed on Nov. 1, 2005.

BACKGROUND OF THE INVENTION

The present invention relates generally to collapsible crates and more particularly to a collapsible crate with support members for supporting another container thereon.

Collapsible crates are well known. Four walls each connected via a hinge to a base are selectively movable about the hinge between a use position, in which the wall is generally perpendicular to the base, and a collapsed position onto the base. Various mechanisms have been provided to connect adjacent walls at the corner to selectively lock the crate in the use position.

SUMMARY OF THE INVENTION

The present invention provides a collapsible container having a plurality of walls collapsible onto the base. At least one wall has a support mounted to an upper end portion thereof.

In one example embodiment, the support is pivotably mounted to an upper end portion of the at least one wall. The support is pivotable between a support position where it is partially supported on an adjacent wall and a retracted position. In the retracted position, the wall can be pivoted downward onto the base, with a portion of the support passing through a channel formed on the interior of the adjacent wall.

In another example, the support is integrally formed with the upper portion of the at least one wall.

The supports may be formed on short end walls of the container, such that the supports and end walls can be collapsed onto the base and the long side walls can be pivoted onto the end walls. In this manner, the supports are protected from damage during shipping of the containers in the collapsed position. The supports may also be formed on long side walls of the container, such that the supports and side walls can be collapsed onto the base and the short end walls can be pivoted onto the side walls.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, a container 10 includes a base 12 having upstanding side walls 14 (or long walls) and upstanding end walls 18 (or short walls). The side walls 14 and end walls 18 are pivotably connected along long and short edges of the base 12, respectively. The side walls 14 and end walls 18 are movable between the upright position shown and a collapsed position on the base 12.

Each end wall 18 has a support 20 (or flap) pivotably mounted to an upper portion thereof. The supports 20 are shown in FIG. 1 pivoted to a support position generally perpendicular to the end walls 18 and projecting into the interior of the container 10. In the support position, laterally-extending tabs 21 are supported on the side walls 14.

The interiors of the side walls 14 each include an upper frame portion 22 protruding into the container 10. A pair of curved channels 24 is formed through each upper frame portion 22. The interiors of the side walls 14 each further include a lower frame portion 26 having a pair of channels 28 formed therethrough. A recess 30 is defined between the upper frame portion 22 and the lower frame portion 26. The base 12 includes a pair of side upstanding portions 32 to which the side walls 14 are pivotably attached. Each side upstanding portion 32 includes a pair of channels 34 formed on an interior thereof. The channels 24, 28 and 34 are aligned with one another in a manner that will be explained below. The base 12 further includes a pair of end upstanding portions 36 to which the end walls 18 are pivotably attached.

Referring to FIG. 2, with the supports 20 in the support position, another container 100 can be supported on the supports 20 of the container 10.
